## Background
RELATED APPLICATIONS
The present invention is a continuation of, was first described in, and claims the benefit of U.S. Provisional Application No. 62/076,757, filed Nov. 7, 2014, the entire disclosures of which are incorporated herein by reference.


FIELD OF THE INVENTION
The present invention relates generally to a hauling device adapted to be towed and manipulated.
BACKGROUND OF THE INVENTION
Maintenance of one's lawn, landscaping, and garden is a seemingly never-ending task. Depending upon the size of the yard/garden, there are a countless number of chores that require the attention of the owner. Mowing the lawn, raking, trimming, mulching, pulling weeds, planting, the list goes on and on.
One (1) popular tool used by many to aid in the growth and beauty of one's lawn and/or garden is the wheelbarrow. This tool allows for easy transport of leaves, grass clippings, yard material, and the like. However, the wheelbarrow requires a good deal of physical strength to move it, as half of the weight of the contents must be borne by the person moving the wheelbarrow. It also requires even more physical strength to lift the wheelbarrow to dump the contents. As a result, the requirement of physical strength makes it unsuitable for use by children, elderly, and those with diminished physical strength.
Accordingly, there exists a need for a means by which yard and garden tasks can be accomplished in a simple and easy manner without the above-mentioned difficulties associated with traditional wheelbarrow use. The use of the hauling device provides for all of the advantages of a wheelbarrow, but without the inherent disadvantage of lifting, balancing, and moving a conventional wheelbarrow.
SUMMARY OF THE INVENTION
The inventor has recognized the aforementioned lack in the art and observed that there is a need for a hauling device adapted to be towed and manipulated.
It is therefore an object of the invention to provide an apparatus first comprising a cart frame. The cart frame has a tongue, a hitch connector, a support plate, a first tube and a second tube. The first and second tubes each have a pivot aperture disposed in a distal end. The hitch connector is attached to an upper face distal end of the tongue. The support plate is attached to a distal end of the tongue opposite the hitch connector as well as to the cart frame first and second tubes. The cart frame is capable of being attached and towed by a vehicle.
The apparatus next comprises a tub frame. The tub frame has a rectangular, tubular metal structure comprising a pair of parallel lateral members, a first cross member, a second cross member and a third cross member. The pair of parallel lateral members are connected at each end by the first cross member and the third cross member respectively. The pair of parallel lateral members are connected by the second cross member at perpendicular points between the first cross member and the third cross member. On the underside of the second cross member is a plurality of clevis brackets with each having a clevis bracket aperture. The apparatus next comprises a tub which is either securely or removably attached to the tub frame which is capable of pivotally motioning the tub relative to the cart frame. The apparatus last comprises a hydraulic lifting mechanism.
The cart frame further comprises a “U”-shaped stand secured to an underside of the support plate with of a pair of stand pivots. Each pivot aperture is configured to accommodate insertion of a dump pivot pin when the pivot apertures are aligned with the clevis bracket apertures in the tub frame. The support plate has a central planar portion and down turned perpendicular flanges.
The tub frame further comprises at least two (2) wheels, an axle having a first and second end and a pair of tube handles. One (1) of the two (2) wheels are attached to the first end of the axle and one (1) of the two (2) wheels are attached to the second end of the axle. The axle is attached to the first lateral member and to the second lateral member. Each of the tube handles are joined to the tube frame by a handle pin extending outwardly.
The hydraulic lifting mechanism is mounted to an upper face of the side furthest from the hitch connector of the first and second tube. The hydraulic lifting mechanism further comprises a jack. The jack comprises a lift arm, a platen disposed upon the lift arm, a jack actuator and a dump valve. The dump valve in a closed position permits transfer of fluid into an internal cylinder through reciprocating motioning of the jack actuator. The internal cylinder is in mechanical communication with the platen via the lift arm. The platen is in mechanical communication with the bottom of the tub.
The tub further comprises a wheelbarrow tray having a sloped, planar bottom and flaring, encircling sidewalls formed in one piece defining a hollow interior. The sidewalls have a peripheral lip. The tub further comprises a cover removably attached to the sidewalls and the removable cover has a shape coextensive with the peripheral lip. There is an auxiliary basket attached to a portion of the cart frame with a plurality of basket brackets. The auxiliary basket further comprises a hollow rectangular or cubic prism.

A tongue 92 is a central, proximal member of the cart frame 90. The tongue 92 is preferably a square metal tube having a commercially available hitch connector 94 attached at a front end thereof. It should be understood that the utilization of a particular hitch connector 94 does not preclude the use of any other style, or method, of attachment to a motive vehicle in any other embodiment and should not be seen as a limiting factor to the scope or intent of the apparatus 10. The length of the tongue 92 should be dictated by the desired distance between any other part of the apparatus 10 and any part of the tow vehicle in the shortest turn radius which the vehicle can accomplish. A support plate 96 is attached to a distal end of the tongue 92 preferably by means of threaded fasteners of some type inserted into appropriate apertures. The support plate 96 is a formed metal plate having a central planar portion and down turned perpendicular flanges yielding a section profile of a shallow, inverted “U”. Attached to a front end of the downturned flanges is a “U”-shaped stand 98. The stand 98 is configured to be a metal strap formed into the appropriate shape and attached to the support plate 96 by means of a stand pivot 102 on either side of the support plate 96. The stand pivots 102 are preferably headed and threaded fasteners with retaining nuts tightened to a sufficient torque to disallow any relative motion such that the stand 98 could be rotated to any selected position between perpendicular to the support plate 96 and parallel thereto. The purpose of the stand 98 is to support the tongue 92 and any attached hitch connector 94 in an elevated position when the apparatus 10 is not connected to a tow vehicle with the stand 98 oriented in a perpendicular position to the tongue 92.
Attached to an upper face of the support plate 96, preferably by welding, are a first tube 104a and a second tube 104b. The first tube 104a and the second tube 104b are preferably square metal tubes which constitute the central support structure for the tub frame 30. The first tube 104a and the second tube 104b are configured to be rounded at a distal end with each having a pivot aperture 106 disposed therein. The pivot apertures 106 are to accommodate the insertion of a dump pivot pin 108 into each of the first tube 104a and the second tube 104b when the pivot apertures 106 are aligned with the clevis bracket apertures 84 in the tub frame 30 as depicted in FIG. 5. The dump pivot pin 104 is configured to be a headed metal pin having an aperture (not shown) for the insertion of a pivot pin retainer 109. The pivot pin retainers 109 may be any of a style of commercially available, quick attachment, spring type, cotter pins sized appropriately to be accommodated within the apertures (not shown) of the dump pivot pins 108.
A commercially available hydraulic jack 110 is adapted to be mounted to an upper face of each of the first tube 104a and the second tube 104b. The jack 110 is preferably attached to the tubes 104a, 104b by means of a plurality of threaded jack fasteners 112 inserted through apertures (not shown) drilled into the tubes 104a, 104b and secured with threaded retainers (not shown). A lift arm 111 is pivotally attached to the frame of the jack 110 and functionally controlled by a jack actuator 116. When the apparatus 10 is fully assembled, as depicted in FIG. 1, a platen 118 of the lift arm 111 is configured to be in contact with the exterior of the bottom 22 of the tub 20. A user may place selected material into the interior 26 of the tub 20 in this configuration. The preferred jack 110 is provided with a rotationally activated dump valve 115 and the reciprocating jack actuator 116. In a closed position the valve 115 enables a user to pump fluid into an internal cylinder (not shown) by manipulating the jack actuator 116 with a jack lever 114. The internal cylinder is in mechanical connection to the platen 118, via the lift arm 111, which is generally configured to be a disk-shaped plate. As fluid pressure is increased within the hydraulic cylinder the lift arm 111 and the platen 118 will be raised thereby lifting the bottom 22 of the tub 20 and rotating the tub frame 30 about the dump pivot pins 118, now inserted between the tubes 104a, 104b and the clevis brackets 82 and allowing the contents of the tub 20 to spill out as shown in FIG. 4. In an open position, the valve 115 will permit fluid to be exhausted from the cylinder allowing the lift arm 111 and the platen 118 to descend to the original position returning the tub 20 to a more horizontal position as depicted in FIG. 1. The jack lever 114 supplied with the apparatus 10 is configured to be a metal rod having an outside diameter capable of being inserted into the jack actuator 116. The jack lever 114 has an offset bend near a first end to provide a clearance with certain parts of the tub frame 30 while operating the jack actuator 116. A second end of the jack lever 114 is provided with a recess 117 into which the valve 115 can be inserted to provide the necessary leverage for rotationally turning. These are all, more or less, standard features of commercially available jacks 110 and should be familiar to persons skilled in the art.
Referring now to FIG. 5, an isolated view of the apparatus 10, depicted with the tub frame 30 separated from the cart frame 90, according to the preferred embodiment of the present invention, is disclosed. A user may, at their discretion, remove the dump pivot pins 108 from the clevis brackets 82 of the tub frame 30 and the apertures at the distal ends of the first tube 104a and the second tube 104b as illustrated in FIG. 3. The dump pivot pins 108 constitute the only physical connection between the tub frame 30 and the cart frame 90.
The preferred embodiment of the present invention can be utilized by an enabled individual in a simple and straightforward manner with little or no training After initial purchase or acquisition of the apparatus 10, it would be installed as indicated in FIG. 1.
